Corresponding key element or the corresponding item put down in writing among symbolic representation accompanying drawing in the above-mentioned parantheses and the embodiment of enforcement utility model described later.

Adopt automobile of the present utility model gap sealing bar and manufacture method thereof, owing to being the metal wool core that corrugated metal wool body is formed by connecting with the non-heat fusing line that can under the sulfuration design temperature, not melt what bury underground along the installation base portion of installing on the flange of the car door peristome circumferential edge setting of vehicle body, therefore when automobile was vulcanized extrusion molding with the gap sealing bar, non-heat fusing line can not melt and can former state keep.Thereby, when automobile is carried out extrusion molding with the gap sealing bar, even while use powerful tensile wire core to make, also can by non-heat fusing line be used for prevent that automobile from together excessively being stretched with gap sealing bar and metal wool core.And improved afterwards the rigidity of installation base portion in shaping, thereby improved the fastening force for flange.

At least in the car outside and car inboard two non-heat fusing lines are set, the non-heat fusing line in the car outside is configured in from the bending starting position that is bent into the formation car outside shoulder of the metal wool body of U font roughly, until make hollow sealing section inboard root by in the car door Monday side the scope of the position of spot projection on the metal wool body in, simultaneously the inboard non-heat fusing line of car is configured in from the bending starting position that is bent into the inboard shoulder of formation car of the metal wool body of U font roughly, until make in the scope by the position of spot projection on the metal wool body of open end one side of car inside side walls of root of claw of open end one side of car inside side walls of the most close installation base portion, therefore especially can by the non-heat fusing line in the configuration car outside make connect the non-heat fusing line in the car outside and the position of the inboard non-heat fusing line of car straight line from the car inboard towards car outside, thereby the outer circumferential side from car door behind closing of the door tilts towards interior all sides (from the peristome side direction connecting wall side of base portion is installed).

Because the position of intersecting with hollow sealing section after the straight line that tilts therefrom prolongs is compared with conventional example (Fig. 9), interior all sides (from peristome sidesway that base portion is installed to the connecting wall side) have been moved on to from the outer circumferential side of car door, therefore after automobile is assembled in the body side corner part of automobile with the gap sealing bar, the sphere of action of convergent force in hollow sealing section just narrows down, and suppressed the generation of wrinkle.

In addition, tilt by the straight line that makes the position that connects the car non-heat fusing line in the outside and the inboard non-heat fusing line of car, can increase the car inside side walls of installation base portion for the fastening force of flange, can keep fully flange by the claw that is arranged on car inside side walls one side.

Thus, automobile stably can be assembled into the body side corner part of automobile with the gap sealing bar, can continue afterwards to keep this stable state in assembling again.

In addition, the utility model is made as from the bending end position that is bent into the formation car outside shoulder of the metal wool body of U font roughly by the scope that will configure the non-heat fusing line in the car outside, rather than from the bending starting position, thereby the position of the non-heat fusing line in the car outside is changed on the side wall portion of the car outside from the connecting wall that base portion is installed, therefore the balance during connection metal line body improves, thereby can prevent effectively that automobile is excessively stretched together with gap sealing bar and metal wool core when automobile is carried out extrusion molding with gap sealing bar and the inboard non-heat fusing line of car.

And the utility model begins from the position that the collocation point that makes the non-heat fusing line in the car outside is projected in the car inboard on the metal wool body the configuration scope of the inboard non-heat fusing line of car and is further qualified, or from blank part one side that is connected to hollow sealing section by in the car door Monday side the straight line of collocation point of the non-heat fusing line of point and the car outside begin with the inboard crossing position of the car of metal wool body and be further qualified, or from connect hollow sealing section by in the car door Monday side the straight line of collocation point of the non-heat fusing line of point and the car outside begin with the inboard crossing position of the car of metal wool body and be further qualified, therefore, the position of intersecting with hollow sealing section after the straight line that tilts therefrom prolongs is just from the more close interior all sides of the outer circumferential side of car door (from the peristome side of installation base portion to the connecting wall side), by this, after automobile is assembled into the body side corner part of automobile with the gap sealing bar, the sphere of action of convergent force in hollow sealing section can further narrow down, and can suppress wrinkle and occur.

And, car inside side walls that base portion is installed is further increased the fastening force of flange, can keep fully flange by the claw of being located at car inside side walls one side.

Yet, no matter at which scope (F1 shown in the aftermentioned embodiment, F2, F3, F4) in, all to arrive near the position of the open end side of car inside side walls the car inside side walls that makes the most close installation base portion in one or more claws open end one side the claw root by that spot projection of open end one side of car inside side walls till the position on the metal wool body, be configured on the position of open end side if cross this position, then after automobile is assembled into the body side corner part of automobile with the gap sealing bar, automobile can not become desirable assembled state with the run-off the straight of gap sealing bar self possibility.

But, when with car inboard non-heat fusing line be configured in from connect hollow sealing section by in the car door Monday side the straight line of collocation point of the non-heat fusing line of point and the car outside with the inboard crossing position of the car of metal wool body, until make the most close installation base portion in one or more claws the car inside side walls open end one side claw root by the scope of the position of spot projection on the metal wool body of open end one side of car inside side walls the time, the straight line prolongation position rear and that hollow sealing section is crossing of the position of the non-heat fusing line of non-heat fusing line and car inboard just is on the point that leans on car door interior Monday of side most of hollow sealing section outside the connection car, or than locating in week in the more close car door of this point, therefore after automobile is assembled into the body side corner part of automobile with the gap sealing bar, can not act on convergent force in hollow sealing section.

In addition, when with car inboard non-heat fusing line be configured in blank part one side that is connected to hollow sealing section by in the car door Monday side straight line and the inboard crossing position of the car of metal wool body of collocation point of the non-heat fusing line of point and the car outside on the time, the position of intersecting with hollow sealing section after the straight line that connects the position of the car non-heat fusing line in the outside and the inboard non-heat fusing line of car prolongs just is in behind the closing of the door on the point all in the most close car door of blank part one side of hollow sealing section, therefore after automobile is assembled into the body side corner part of automobile with the gap sealing bar, the convergent force that acts on hollow sealing section just acts on the thickness of sky sealing, therefore hardly wrinkle can occur.And, when the straight line of the collocation point of the non-heat fusing line of the point in week and the car outside and the inboard position of intersecting of the car of metal wool body begin more position on the metal wool body of that spot projection near open end one side of leaning on the car inside side walls of the root of the claw of open end one side of the car inside side walls that makes the most close installation base portion in one or more claws in the collocation point of the inboard non-heat fusing line with car is located at than the most close car door of blank part one side that is connected to hollow sealing section, after the straight line that connects the position of the car non-heat fusing line in the outside and the inboard non-heat fusing line of car prolongs and the hollow sealing section position of intersecting just be in than behind the closing of the door in the most close car door of blank part one side of hollow sealing section Monday side the more close car door of point in the position in week, therefore, wrinkle just more can not occur.

In addition, therefore metal wool body of the present utility model can bear very strong tensile force except by also connecting partly by the meeting heat fusing line that fusing is also roughly extended along its length point-blank under the sulfuration design temperature the non-heat fusing line before sulfuration.And, the heat fusing line is configured in respectively on the connecting wall that base portion is installed, on the position of installing on the car outside sidewall of base portion than the open end of the more close car of the collocation point outside sidewall of the non-heat fusing line in the car outside, and on the position of installing on the car inside side walls of base portion than the open end of the more close car inside side walls of collocation point of the inboard non-heat fusing line of above-mentioned car, therefore balance is good, and can disappear through over cure after heat fusing line, therefore after automobile is assembled into the body side corner part of automobile with the gap sealing bar, can not become the factor that causes hollow sealing section flexible.

In addition, the utility model is provided with the nappe that proportion is higher than the material that base portion is installed at the car outside shoulder that base portion is installed, therefore can stably automobile be assembled into the body side corner part of automobile with the gap sealing bar, and also can wrinkle not occur in this part.But also can utilize the strength of material at this position and the inboard non-heat fusing line of car is become the heat fusing line.

The line 22 that stretches in the longitudinal direction for inhibition metal wool body 21 is non-heat fusing lines, when in the manufacturing process of automobile with gap sealing bar 10, making the rubber constituent sulfuration, non-heat fusing line can not melt under the sulfuration design temperature, respectively arrange one in the car outside and car inboard, add up to two non-heat fusing lines 221,222 are set.

And, the allocation position of the car non-heat fusing line 221 in the outside and the inboard non-heat fusing line 222 of car is carried out following concrete restriction.

It at first is the non-heat fusing line 221 in the car outside, as shown in Figure 1, be bent into U font roughly and be embedded under the state that base portion 11 is installed at metal wool body 21, the allocation position of non-heat fusing line 221 is limited in the scope R1, and this scope R1 is that the point 51 by all sides in the car door from the bending starting position 21c of the formation car outside shoulder 21a that is bent into the metal wool body 21 of U font roughly to the inboard root 12a that makes hollow sealing section 12 is projected in till the position 52 on the metal wool body 21.And if the position of non-heat fusing line 221 is positioned at shoulder 21a place, the car outside, then because when metal wool body 21 is bent to state shown in Fig. 2 (b) from the deployed condition shown in Fig. 2 (a), non-heat fusing line 221 can be offset at shoulder 21a place, the car outside, therefore non-heat fusing line 221 had better not be configured in shoulder 21a place, the car outside.Thereby, the non-heat fusing cotton rope 221 in the car outside can be configured in the scope R2, this scope R2 is that the point 51 by all sides in the car door from the bending end position 21d that is bent into the formation car outside shoulder 21a of the metal wool body 21 of U font roughly to the inboard root 12a that makes hollow sealing section 12 is projected in till the position 52 on the metal wool body 21.

If with the configuration circumscription of the non-heat fusing line 221 in the car outside for from the bending end position 21d that is bent into the formation car outside shoulder 21a of the metal wool body 21 of U font roughly, rather than from bending starting position 21c, then the position of the non-heat fusing line 221 in the car outside just changes on the side wall portion 11a of the car outside from the connecting wall 11c that base portion 11 is installed, therefore, balance in the time of can making connection metal line body 21 improves, thereby in the time of effectively preventing from the same time automobile being carried out extrusion molding with gap sealing bar 10 and the inboard non-heat fusing line 222 of car, automobile is excessively stretched with metal wool core 20 with gap sealing bar 10.

Then be the inboard non-heat fusing line 222 of car, as shown in Figure 1, be bent to U font roughly and be embedded under the state that base portion 11 is installed at metal wool body 21, the allocation position of non-heat fusing line 222 is limited in the scope F1, this scope F1 be from the bending starting position 21e of the inboard shoulder 21b of formation car that is bent into the metal wool body 21 of U font roughly till make following point 53 be projected in position 54 on the metal wool body 21, wherein, point 53 is (to be to be claw 13 at the claw of installing on the car inside side walls 11b of base portion 11 by open end one side herein, because a claw 13 only being arranged, therefore, this point 53 is exactly at this claw 13) the point of open end one side of depending on car inside side walls 11b of root.But, if the position of non-heat fusing line 222 is positioned at the inboard shoulder 21b of car place, then when metal wool body 21 is bent into state shown in Fig. 2 (b) from the deployed condition shown in Fig. 2 (a), non-heat fusing line 222 can be offset at the inboard shoulder 21b of car place, therefore, non-heat fusing line 222 had better not be configured in the inboard shoulder 21b of car place.Thereby, the allocation position of the inboard non-heat fusing cotton rope 222 of car can be limited to following scope, this scope from the bending end position 21f of the inboard shoulder 21b of formation car that is bent into the metal wool body 21 of U font roughly till make following point 53 be projected in position 54 on the metal wool body 21, wherein, 53 is points by open end one side of car inside side walls 11b of the root of claw 13.

If with the configuration scope dictates of the inboard non-heat fusing line 222 of car for from the bending end position 21f that is bent into the inboard shoulder 21b of formation car of the metal wool body 21 of U font roughly, rather than from bending starting position 21e, then the position of the inboard non-heat fusing line 222 of car just changes on the car inside side walls 11b of section from the connecting wall 11c that base portion 11 is installed, therefore, balance in the time of can making connection metal line body 21 improves, thereby in the time of effectively preventing from the same time automobile being carried out extrusion molding with the non-heat fusing line 221 of gap sealing bar 10 and the car outside, automobile is excessively stretched with metal wool core 20 with gap sealing bar 10.

In addition, can also be in scope F1 the position of the inboard non-heat fusing line 222 of car be limited in the narrower range F2, this scope F2 is projected in the car inboard on the metal wool body 21 from the collocation point that makes the non-heat fusing line 221 in the car outside position 55 is till make following point 53 be projected in position 54 on the metal wool body 21, wherein, 53 is points by open end one side of car inside side walls 11b of the root of claw 13.

Can also be in scope F2 the position of the inboard non-heat fusing line 222 of car be limited in the narrower range F3, this scope F3 from straight line 100 and the inboard position 57 of intersecting of the car of metal wool body 21 till make following point 53 be projected in position 54 on the metal wool body 21, wherein, point 53 is points by open end one side of car inside side walls 11b of the root of claw 13, above-mentioned straight line 100 will the empty side of hollow sealing section 12 by in the car door Monday side point (all side ends car door in) 56 be connected with the collocation point of non-heat fusing line 221 outside the car.

Like this, except the configuration car non-heat fusing line 221 in the outside and the inboard non-heat fusing line 222 of car, can also be as shown in Figure 3, being used under the sulfuration design temperature can fusing and be along its length the heat fusing line 23 that roughly extends point-blank with 21 local connections of metal wool body.At this, be bent into U font roughly and be embedded under the state that base portion 11 is installed at metal wool body 21, configure altogether five heat fusing lines 23, wherein, install on the connecting wall 11c of base portion 11 except two shoulder 21a, two have been configured on the part outside the 21b, the position of open end one side of sidewall 11a has configured two outside the more close car of collocation point that the non-heat fusing line 221 in the ratio car outside on the car outside sidewall 11a of base portion 11 is installed, and the position of open end one side of the more close car inside side walls of the collocation point 11b of the inboard non-heat fusing line 222 of the ratio car on the car inside side walls 11b that base portion 11 is installed has configured one.

In addition, also can increase non-heat fusing line 22.In Fig. 3, the position of more close connecting wall 11c one side of collocation point of the inboard non-heat fusing line 222 of the ratio car on the car inside side walls 11b that base portion 11 is installed arranges two non-heat fusing lines 22 (223 and 224), thereby has improved the stretch-proof intensity of force.

Like this, metal wool body 20 is except also can vulcanizing 23 local connections of heat fusing line of melting under the design temperature and roughly extending point-blank along its length, therefore, being born very strong tensile force the non-heat fusing line 22 before sulfuration.In addition, heat fusing line 23 is configured in respectively on three limits that base portion is installed, therefore balance is good, and through the 23 meeting disappearances of over cure after heat fusing line, therefore, after automobile is assembled into the body side corner part of automobile with gap sealing bar 10, can not become the factor that causes hollow sealing section 12 to be stretched.

Herein, non-heat fusing line 22 (221,222,223,224) refer to melting point for example be 230～280 degree (℃), when extrusion molding (approximately 100 degree (℃)) and at vulcanizing oven (200～250 degree (℃)) in the line that all can not melt, can consider to be consisted of by alkide resin (for example PET (polyethylene terephthalate)) or amilan (for example 6 nylon, 6-6 nylon).

In addition, heat fusing line 23 refer to melting point for example be 100～160 degree (℃), during extrusion molding (approximately 100 degree (℃)) can not melt but at vulcanizing oven (200～250 degree (℃)) in the line that can melt, can consider to be consisted of by polyolefin resin (for example PP (polypropylene), PE (polyethylene)).

In addition, automobile is to be made of elastomeric materials such as EPDM with gap sealing bar 10, but also can be made of other elastomeric material.In addition, use sponge material (for example EPDM sponge) at the sealing surface of hollow sealing section 12, and use solid-state material (for example EPDM solid material) in other parts, but be not particularly limited.

Below, with reference to Fig. 4 and Fig. 5, an automobile shown in Figure 3 example with the manufacture method of gap sealing bar 10 is described.

At first, supply with in the operation at metal wool carrier (W/C), shown in Fig. 5 (a), send into the metal wool core 20 that is deployed condition from metal wool carrier (W/C) feedway 41.The metal wool body 21 of metal wool core 20 passes through four non-heat fusing lines 22 (221,222,223,224) and is connected along its length partly connection of a heat fusing line 23.

At this moment, as mentioned above, non-heat fusing line 221 is configured in advance as follows: shown in Fig. 3 and Fig. 5 (d), be bent into U font roughly and be embedded under the state (states of final products) that base portion 11 is installed at metal wool body 21, the position of non-heat fusing line 221 is in the scope R1 and avoids car outside shoulder 21a part, this scope R1 be from the bending starting position 21c that is bent into the formation car outside shoulder 21a of the metal wool body 21 of U font roughly to the inboard root 12a that makes hollow sealing section 12 by in the car door Monday side point 51 be projected in position 52 on the metal wool body 21 till.

And, as mentioned above, non-heat fusing line 222 is also configured in advance as follows: shown in Fig. 3 and Fig. 5 (d), be bent to U font roughly and be embedded under the state that base portion 11 is installed at metal wool body 21, the position of non-heat fusing line 222 is in the scope F1 and avoids the inboard shoulder 21b of car part, and this scope F1 is that the point 53 by open end one side of car inside side walls 11b from the bending starting position 21e that is bent into the inboard shoulder 21b of formation car of the metal wool body 21 of U font roughly to the root that makes claw 13 is projected in till the position 54 on the metal wool body 21.

And, as mentioned above, heat fusing line 23 is also configured in advance as follows: shown in Fig. 3 and Fig. 5 (d), after metal wool body 21 is bent into U font roughly, be embedded under the state that base portion 11 is installed and configure altogether five heat fusing lines 23, namely, install on the connecting wall 11c of base portion 11 except two shoulder 21a, partial configuration outside the 21b two, the collocation point of non-heat fusing line 221 has more configured two by the position of open end one side of sidewall 11a outside the car outside the ratio car of installing on the car outside sidewall 11a of base portion 11, and the collocation point of the inboard non-heat fusing line 222 of the ratio car on the car inside side walls 11b that base portion 11 is installed more leans on the position of open end one side of car inside side walls 11b to configure one.

And, as mentioned above, non-heat fusing line 223,224 is also configured in advance as follows: shown in Fig. 3 and Fig. 5 (d), be embedded in after metal wool body 21 is bent into U font roughly under the state that base portion 11 is installed, non-heat fusing line 223,224 is in the collocation point of the inboard non-heat fusing line 222 of ratio car on the car inside side walls 11b that base portion 11 is installed more by on the position of connecting wall 11c one side.

Then, in the pre-bending operation, shown in Fig. 5 (b), on pre-bending device 42, will be two ends, the cross section bending of the metal wool core 20 of deployed condition, form the cross sectional shape of dish shape.But also can not with the two ends bending, but only an end be bent.

Then shown in Fig. 5 (c), in extrusion process, that make in the cross section that utilizes extrusion press 43 that base portion 11 will be installed is consistent with metal wool core 20 shapes that are pre-bent to dish shape cross sectional shape, peristome is than same dish shape that roughly the U shaped sections is larger (each enlarges approximately 45 degree to peristome to the left and right than U shaped sections roughly), and under the state of burying metal wool core 20 underground automobile is extruded in vulcanizing oven 44 with gap sealing bar 10.At this moment, extrusion molding goes out hollow sealing section 12, claw 13, jut 14, lip 15 and covering section 16 installing on the base portion 11 integratedly.

In addition, be provided with the machine of getting 45 at the outlet side of vulcanizing oven 44, with powerful the metal wool core 20 with automobile with gap sealing bar 10 together from extrusion press 43 extruded stretched on one side, one side guides metal wool core 20 to vulcanizing oven 44.

In vulcanization process, automobile with gap sealing bar 10 in vulcanizing oven 44, be heated to 200～250 degree (℃), make thus rubber constituent sulfuration and guaranteed certain elasticity and intensity.Heat fusing line 23 is because being melted by vulcanizing oven 44, even if but four non-heat fusing lines 221,222,223,224 can not melt by vulcanizing oven yet, therefore, automobile can excessively not stretched with gap sealing bar 10 in vulcanization process.

And on forming maker 46, the automobile after the sulfuration passes through finishing die with gap sealing bar 10, and shown in Fig. 5 (d), peristome is dwindled, and makes the cross section that base portion 11 is installed be roughly U font.

Then implement cooling processing etc., thereby finally produce automobile gap sealing bar 10.

Adopt the automobile gap sealing bar 10 of above-mentioned manufacturing, owing to having buried the metal wool core 20 that corrugated metal wool body 21 is formed by connecting by the non-heat fusing line 22 (221,222,223,224) that can under the sulfuration design temperature, not melt underground at the installation base portion 11 of installing on the flange 3 that around the car door peristome of vehicle body 1, arranges, therefore when automobile was vulcanized extrusion molding with gap sealing bar 10, non-heat fusing line 22 can not melt and can former state keep.Thereby, when automobile is carried out extrusion molding with gap sealing bar 10, even while using powerful tensile wire core 20 to make, also can by non-heat fusing line 22 be used for prevent that automobile from together excessively being stretched with gap sealing bar 10 and metal wool core 20.And improved afterwards the rigidity of installation base portion 11 in shaping, thereby improved the fastening force for flange 3.

And, at least in the car outside and car inboard two non-heat fusing lines 22 are set, the non-heat fusing line 221 in the car outside is configured in the scope R1, this scope R1 from the bending starting position 21c of the formation car outside shoulder 21a that is bent into the metal wool body 21 of U font roughly to the root 12a that makes hollow sealing section 12 inboards by in the car door Monday side point 51 be projected in position 52 on the metal wool body 21 till, and the inboard non-heat fusing line 222 of car is configured in the scope F1, the point 53 by open end one side of car inside side walls of this scope F1 on from the bending starting position 21e of the inboard shoulder 21b of formation car that is bent into the metal wool body 21 of U font roughly to the root that makes claw 13 is projected in till the position 54 on the metal wool body 21, therefore, can make connect the non-heat fusing line 221 in the car outside and the position of the inboard non-heat fusing line 222 of car straight line from the car inboard towards car the outside and tilting from the inside all sides of the outer circumferential side of car door 2 (from the peristome side direction connecting wall 11c side of base portion 11 is installed).

Like this, because the position of intersecting with hollow sealing section 12 after the straight line that tilts prolongs is compared with conventional example (Fig. 9), interior all sides (from peristome sidesway that base portion 11 is installed to connecting wall 11c side) have been moved on to from the outer circumferential side of car door 2, therefore after automobile is assembled in the body side corner part of automobile with gap sealing bar 10, the sphere of action of convergent force in hollow sealing section 12 just narrows down, and suppressed the generation of wrinkle 202.

In addition, tilt by the straight line that makes the position that connects the non-heat fusing line 221 in the car outside and the inboard non-heat fusing line 222 of car, can increase the car inside side walls 11b of installation base portion 11 for the fastening force of flange 3, can keep fully flange 3 by enough claws 13 that is arranged on car inside side walls 11b one side.

Thus, automobile stably can be assembled into the body side corner part of automobile with gap sealing bar 10, can continue afterwards to keep this stable state in assembling again.

Be defined as step by step the scope of F2 from the scope of F1 by the configuration scope with the inboard non-heat fusing line 222 of car, the scope of F3, thereby the position of intersecting with hollow sealing section 12 after the straight line that connects the non-heat fusing line 221 in the car outside and the position of the inboard non-heat fusing line 222 of car is prolonged from the outer circumferential side of car door 2 further near interior all sides (from the peristome side of installation base portion 11 to connecting wall 11c side), therefore after automobile is assembled into the body side corner part of automobile with gap sealing bar 10, the sphere of action of convergent force in hollow sealing section 12 can further narrow down, and can suppress wrinkle 202 and occur.

And the car inside side walls 11b of installation base portion 11 further increases for the fastening force of flange 3, can keep fully flange 3 by enough claws 13 that is arranged on car inside side walls 11b.

In addition, when the scope that the inboard non-heat fusing line 222 of car is configured in F3, namely, be configured in the blank part side that connects hollow sealing section 12 by in the car door Monday side straight line 100 and the inboard position 57 of intersecting of the car of metal wool body 21 of collocation point of the non-heat fusing line 221 of point 56 and the car outside on the time, the position of intersecting with hollow sealing section 12 after the straight line that connects the position of the car non-heat fusing line 221 in the outside and the inboard non-heat fusing line 222 of car prolongs is exactly the point 56 that leans on side Monday in the car door most in the blank part side of hollow sealing section 12, therefore after automobile is assembled into the body side corner part of automobile with gap sealing bar 10, convergent force to hollow sealing 12 just acts on the thickness of hollow sealing section 12, therefore hardly wrinkle 202 can occur.And if the point that will configure the inboard non-heat fusing line 222 of car is arranged on the point 53 by open end one side of car inside side walls 11b than the more close root that makes claw 13 in the inboard position of intersecting of straight line 100 and the car of metal wool body 21 57 and is projected in 54 places, position on the metal wool body 21, the position of intersecting with hollow sealing section 12 after the straight line of the position that connects the car non-heat fusing line 221 in the outside and the inboard non-heat fusing line 222 of car is prolonged than blank part one side of hollow sealing section 12 by in the car door Monday side point 56 also near all sides in the car doors, more wrinkle can not occur therefore.

But, in the present embodiment, compare with the root 12b of the hollow sealing section 12 of extending from the outer fix of car outside sidewall 11a from the root 12a of the hollow sealing section 12 that the inner side of car outside sidewall 11a that base portion 11 is installed extends, interior all sides towards car door 2 lodge more, but also can be as shown in Figure 6, also applicable to the root 12a of the inboard that is positioned at hollow sealing section 12 with outstanding from the car outside sidewall 11a that base portion 11 is installed with the root 12b that is positioned at the outside same angle, namely have automobile that the cross section is the hollow sealing section that splayed roughly extends with gap sealing bar 10.

In addition, in the present embodiment, that configuration circumscription with the inboard non-heat fusing line 222 of car is in scope F3, this scope F3 be from blank part one side that is connected to hollow sealing section 12 by in the car door Monday side straight line 100 and the inboard position 57 of intersecting of the car of metal wool body 21 of collocation point of the non-heat fusing line 221 of point (all side ends in the car door) 56 and the car outside be projected in position 54 on the metal wool body 21 to the point 53 by open end one side of car inside side walls 11b of the root that makes claw 13 till, but also this circumscription can be got narrower.Namely, as shown in Figure 6, in the scope that the is configured in F4 with the inboard non-heat fusing line 6 of car, this scope F4 be from connect hollow sealing section 12 by in the car door Monday side straight line 300 and the inboard position 59 of intersecting of the car of metal wool body 21 of collocation point of the non-heat fusing line 221 of point (all side ends in the car door) 58 and the car outside be projected in position 54 on the metal wool body 21 to the point 53 by open end one side of car inside side walls 11b of the root that makes claw 13 till.

Like this, it is exactly on the point that leans on car door interior Monday of side most of hollow sealing section 12 that the straight line of the position of the non-heat fusing line 222 of the non-heat fusing line 221 in the connection car outside and car inboard prolongs position rear and that hollow sealing section 12 intersects, or than week in the more close car door of this point, therefore after automobile is assembled into the body side corner part of automobile with gap sealing bar 10, can not act on convergent force in the hollow sealing section 12.

In addition, in the present embodiment, be provided with a claw 13 in the inboard of the car inside side walls 11b that base portion 11 is installed, but also a plurality of claws 13 can be set as shown in Figure 7,17 (being 2 herein).In this case, the inboard non-heat fusing line 222 of car just be positioned at claw 13 by open end one side of the car inside side walls 11b of installation base portion 11 in a plurality of claws 13,17 as benchmark by the configuration boundary of open end one side of car inside side walls 11b, and be to make the point 53 of open end one side of depending on car inside side walls 11b of the root of this claw 13 be projected in position 54 on the metal wool body 21.
